关于web页面JApplet打印小票

做这个的例子太少，我把我做的示例亮出来

一.先说说需要的版本

　　1.我用的浏览器只有ie：

　　　　火狐只支持52版本以下，并且是java7、java8。chrome不支持　

　　2.applet客户端打印，需要java6：

　　　　亲自测试，java6需要一些提示是否运行，等都同意后，打印时不用再提示。

　　　　　　　　   在java7、8，我自己测试控制面板里面没有低级，只有高级和超高级，不管什么时候打印，它都会提示是否同意

　　　　所以，我最终还是选择了在applet里放入jre6

二.applet的打印代码

　　1.html,在ie下才可运行

　　因为执行的时候，需要检查有没有jre6、请求/接受路径、一些传递的参数，运行的class、需要的jar，代码如下：

function is_ie(json, print_type) {
        //){
        //项目的根路径
        var req_path = "http://localhost:8080";
        //打印机名
        var print_name = "Deli DL-888C";

        var str = "JRPrinterApplet";
        var archive = 'jbarcodebean-1.2.0.jar,json-20160810.jar,print.jar';
        var codebase = '/applets'
        var file = '/applets/jre-6u45-windows-i586.exe';
        var scriptable = false;
        var type = 'application/x-java-applet;version=1.6.0';
        var clsid = "";
        if (isFamilyVersionSupported()) {
            clsid = "clsid:CAFEEFAC-0016-0000-FFFF-ABCDEFFEDCBA";
        } else {
            clsid = "clsid:CAFEEFAC-0016-0000-0008-ABCDEFFEDCBA";
        }
        var write = '' +
                //'<object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" width = "0" height = "0"  codebase="'+file+'" mayscript>' +
                '<object classid="' + clsid + '" width = "0" height = "0"  codebase="' + file + '" mayscript>' +
                '<param name = "code" value = "' + str + '.class" >' +
                '<param name = "codebase" value = "' + codebase + '" >' +
                '<param name = "archive" value = "' + archive + '" >' +
                '<param name="type" value="' + type + '">' +
                '<param name="scriptable" value="' + scriptable + '">' +
                '<param name = "print_type" value ="' + print_type + '">' +
                '<param name = "print_name" value ="' + print_name + '">' +
                '<param name = "req_path" value ="' + req_path + '">' +
                '<param name = "json" value =\'' + json + '\'>' +
                '<comment>' +
                '<embed type="' + type + '" code="' + str + '.class" java_codebase="' + codebase + '" archive="' + archive + '" scriptable=' + scriptable + ' pluginspage="' + file + '" >' +
                '<noembed></noembed>' +
                '</embed>' +
                '</comment>' +
                '</object>';
        $("#objectDiv").html(write)
        if(print_type=='login_test'){

        }
    }

　　　　　　一定要用java6生成class，要不然applet的java6不支持

　　　　　　(1).将class生成jar，我命名print.jar

　　　　　　(2).jar -cvf print.jar *.class  (生成jar包)，放入applets

　　　　　5.签名　　　　

　　　　　　1.创建一个证书
　　　　　　keytool -genkey -validity 1800 -keystore applet.store -alias applet  
　　　　　　2.导出证书文件
　　　　　　keytool -export -keystore applet.store -alias applet -file applet.cer
　　　　　　3.对jar包进行签名

　　　　　　jarsigner -keystore applet.store jbarcodebean-1.2.0.jar applet

　　　　　　jarsigner -keystore applet.store json-20160810.jar applet

　　　　　　jarsigner -keystore applet.store print.jar applet

　　　　　6.将上面图的那些文件放入applet
